Answer:
I have no idea
Step-by-step explanation:
I have no idea
The volume of a crate is b x l x h. Reverse it to get 3 times 6 times h = 72. 3 times 6 is 18, so you know 18h=72. Divide both sides by 18 to get h = 4 ft.
Eay peasy
solve graphically
graph them and find the poitn that they intersect at
y=mx+b
m=slope
b= y intercept
y=7x-9
slope=7
yintercept=-9
y=3x-1
slope=3
yinercept=-1
I have attached graph below
easier way would be to simply sub them and solve
7x-9=y=3x-1
7x-9=3x-1
4x-9=-1
4x=8
x=2
y=3x-1
y=3*2-1
y=6-1
y=5
(2,5) is solution
Answer:
x=2
Step-by-step explanation:
-3x+7=1
subtract 7 from both sides: -3x+7-7=1-7
simplify: -3x=-6
divide both sides by -3:
simplify: x=2
#3 is the answer
4x+5x is 96 4*8 is 32 5*-3 is -15 32+-15 is 17
